Facts - I have installed mOffice version 3.7.7 on an LG G4 Android phone.

I have installed Mobilsynapse v. 3.1.1 on the Windows 7 computer.

I have installed Microsoft Office Home & Business 2010 on the computer, with Outlook 2010 v, 14.0.7177.5000

Problem - When I use the two-way synch to synch the calendar events between the Outlook 2010 Calendar and the Android Native Calendar on the LG phone, the sychronization routine randomly changes limited duration, recurring, all day events in the Outlook Calendar from the number of recurrances in Outlook to 999 recurrances in the cell phone calendar. It does not chnage all of the recurring events, but perhaps about half of them. I cannot identify the "trigger" that causes some to be changed and others not to be changed. It does not change the dates or the number of recurrances of the events in the Outlook calendar.
